Every part of this unique bird is black, from its metallic feathers to its onyx feet. It even has inky internal organs, an effect caused by a condition called fibromelanosis, a harmless genetic mutation that causes extra melanin to seep into the bird’s tissue. This process happens in embryo, resulting in adorably dark Cemani chicks.

Ayam Cemani has inspired Javanese folklore since the 12th century, when it was considered a bird of the elite. Its charcoal-colored blood is rumored to be a delicacy of spirits that bring power and wealth, making it a good luck charm.
